| Abstract: | Fast Automatic Gain Control system can enlarge the dynamic range of the receiver, and ensure the system response time, A fast peak value detection algorithm is proposed in this paper and applied in the AGC system. The AGC system is implemented on FPGA. The response time of the AGC system is about several microseconds, and is proved by the hardware testing. |
